Abstract: Background　The advent of an aging society is seeing an increased incidence rate of age-related cataract（ARC） in China.Cataract is a common complication of diabetes mellitus.In particular，ARC is often found in diabetics clinically，with manifestations similar to those of ARC in non-diabetics except earlier onset and rapider progress.Most diabetic and non-diabetic cases of ARC without surgery contraindications could be treated with cataract extraction despite of causes，but postoperative outcomes may be different.Objective　To investigate the incidence of postoperative complications in diabetic and non-diabetic cases of ARC，to find out possible targeted preventive and therapeutic interventions.Methods　A retrospective design was conducted.Clinical data of 182 cases of ARC（189 eyes） treated with surgery were collected from the Second Affiliated Hospital of Hainan Medical University from January to December 2017，including 51 diabetics（53 eyes） and 131 non-diabetics（136 eyes）.Postoperative complications at 1 week（corneal edema，fibrous exudation，pupil posterior synechia，anterior chamber hemorrhage，macular edema），postoperative visual acuity recovery at 1 week，1 month and 3 months，and prognosis were compared between the two groups.Results　The incidence of 7-day postoperative complications in diabetics 〔56.9% （29/51）〕was higher than that in non-diabetics 〔18.3% （24/131）〕 （P<0.05）.There was no significant difference in corrected visual acuity between the two groups at 1 week，1 month and 3 months after operation（P>0.05）.One month after operation，3 diabetic cases（4 eyes，7.55%，4/53） had poor wound healing，while no non-diabetics occurred.The 30-day postoperative outcome was significantly different between the two groups（P<0.05）.Conclusion　Diabetics with ARC may be more prone to postoperative complications，which should be paid more attention to.To obtain better prognosis for such patients，active measures should be taken to reasonably control blood glucose before operation and choose reasonable operation time to reduce postoperative complications as much as possible.

摘要： 背景　老龄化社会的到来使得国内年龄相关性白内障（ARC）的发病率升高。白内障是糖尿病常见的并发症，其中糖尿病合并ARC临床较多见，其临床表现与ARC相似，但发病较早、进展快。不同病因所致的老年白内障，如无手术禁忌证，多可行白内障手术治疗，但其术后的临床结局不尽相同。目的　探讨糖尿病合并ARC与ARC患者术后并发症的发生状况，分析临床可采取的防治措施。方法　对海南医学院第二附属医院2017年1—12月收治的182例（189眼）行白内障手术老年患者的临床资料进行回顾性分析，其中糖尿病合并ARC患者51例（53眼）作为观察组，ARC患者131例（136眼）作为对照组。比较两组术后1周并发症（角膜水肿、纤维性渗出、瞳孔后粘连、前房出血、黄斑水肿），术后1周、1个月、3个月矫正视力及预后情况。结果　观察组术后1周并发症发生率〔56.9%（29/51）〕高于对照组〔18.3%（24/131）〕（P<0.05）。两组术后1周、1个月、3个月矫正视力情况比较，差异无统计学意义（P>0.05）。术后1个月观察组3例（4眼，7.55%，4/53）切口愈合不良，对照组0例；两组术后1个月预后情况比较，差异有统计学意义（P<0.05）。结论　糖尿病合并ARC患者术后并发症发生率更高，应引起临床的高度重视，需采取积极措施合理控制术前血糖，选择合理的手术时机，尽可能减少术后并发症，以使患者获得更佳的预后。
